Abstract
A level wind system suitable for winding an elongated sonar array onto and off from a storage drum includes a guide member which guides the array into a counterbalanced free pivoting arm having a large radius arcuate section terminating substantially in tangential relationship to said drum and which uses the tension force on the array to continually reposition itself relative to each previous wrap on the drum. A series of rollers are located on the inside surface of the arm to guide the array and to minimize the forces on the array. A pair of spring-loaded rollers are positioned between the storage drum flanges which hold the array in position and prevent slack from developing during power-off situations.
